Host: Nora Ludewig    Shownoter: Jochen Spalding Gast: Etienne Benson I wanted to make an episode on a topic from the history of science for a long time, finally it happened. This is an interview with Etienne Benson, professor of the history of science and technology, on the history of how people of the western world have been seeing, studying and explaining their environment. We talk mostly about his book, Surroundings, but also briefly about his current field of study.

A quick update on why there’s so few episodes from Markus and Nora. In English and German.

Guest: Antoine van Gent    Host: Markus Völter    Shownoter: Pascal Becker In July I visited the Airbus Helicopters factory in Donauwörth and spent time with Antoine van Gent, the Head of Development Flight and Ground testing for . We talked about the helicopter flight testing process, some of the cultural aspects, the collaboration between pilots and the flight test engineer as well as his participation in a landing of an H145 on top of the Aconcagua mountain.

Guest: Peter Psarras    Host: Markus Völter    Shownoter: Simon Bretschneider The climate situatation is getting more and more dire, and in order to reach the goals the international community has set for themselves, engineering solutions seem increasingly necessary. After talking about solar geoengineering in episode 385, we will look at direct air capture in this episode. Direct Air Capture is a family of technologies that allow the extraction of CO2 from the atmosphere. My guest Peter Psarras explains the technology, the economics and also the political and moral challenges associated with the technology.

Gast: David Keith    Host: Markus Völter    Shownoter: Alexander Grote The root cause of global warming is that more and more of the energy supplied by the sun is captured by the atmosphere because of increased amounts of CO2 and other climate gases. One way of fixing this is to make sure that more of that energy is reflected and never even penetrates the lower atmosphere. Solar geoengineering proposes to put particles into the upper atmosphere to increase its reflectivity and thereby reduce the temperature. In the episode I talk with Harvard’s David Keith about some of the technical aspects, which role this technique can play in the overall fight against climate change, some of the political challenges as well as current avenues of research.

Gast: Markus Völter   Host: Marco Calviani    Shownoter: Kolja Dummann The beam dump is a large graphite block used to take up the energy stored in the LHC beam in case the beam needs to be shut down. Since the energy in the beam can be as high as the kinetic energy of a landing 747-400, deg and operating the dump is challenging. In this episode, Marco Calviani, who heads the group that is responsible for this and other beam dumps at CERN, tells us about how the dump works, and what they have recently changed in order to cope with the higher luminosity in future configurations of the LHC.

It's been 377 episodes and we have not yet dedicated one to the F-18. This changes now. In the episode we first talk with Jerry Deren, a former US Navy Hornet pilot who also flew with the Blue Angels; we cover both aspects of his career. In part two we chat with Nick Anderson, former RAAF F-18 pilot (and co-host of the Airline Pilot Guy podcast). We chat about his experience flying the Hornet Down Under, focussing on quirks and funny stories.

The main part of this episode is about flying the F-22 Raptor, the most modern air superiority fighter in the inventory of the USAF. Our guest is Dan Javorsek, callsign Animal, who has previously flown the Raptor in operational test. Dan has also been the initiator of the Alpha Dogfight trials, where an AI was tested against a real pilot in a simulator air-to-air engagement. Dan also flew the F-117 and the F-35, so we cover those airplanes as well.

In this episode I talk with Paulo Iscold, a professor or aeronautical engineering at Cal Poly about Nixus Nixus, his most recent project. Nixus is one of the most fascinating and ground-breaking research efforts in the space of gliding. It uses advanced manufacturing techniques to a very thing wing, plus a fly-by-wire system to control the ailerons and the flaps; the latter are automatically adjusted to the current speed.

In this episode we cover the final storage of nuclear waste in underground facilities. We start out with a conversation about the basic process and the chemistry and physics of nuclear waste with Gareth Law, a professor of radiochemistry at the university of Helsinki. We then discuss geological issues with Heini Reijonen of the Geological Survey of Finland. Our third conversation is about the Onkalo storage facility in Finland with Sophie Haapalehto, who works for Posiva, the operator of the site.

My guest Jens and I have two things in common: we both fly gliders, and we both got to fly in an F-16. Which is why we form the Viper Gliding Club :-) Jens is a Danish journalist and got to fly with the Danish Air Force in one of their F-16Bs. In this episode we compare notes on our experiences, appreciate the commonalities and discuss the differences.

A while ago we had a whole series about LHC, ATLAS and particle physics in general. However, despite all we know and the explanatory power of the standard model, there is also a variety of open questions and currently unexplained phenomena. These include dark matter, dark energy, the neutrino mass, the violation, the hierarchy problem, and of course the unification of the standard model with gravitation. In this episode, CERN's Valerie Domcke explains what it's all about.

In this episode we take a look at newer generations of fission reactors, those that are currently being developed or researched. Our guest is Jacopo Buongiorno of MIT. We discuss some of the high-level goals of these new reactors, such as increased safety and efficiency, and then look at a few of the interesting new designs and how they realize these goals. We also briefly cover some of the policy arguments around keeping fission in the mix for combatting climate change.

In this episode we look at how supercomputers are used to help with managing the pandemic. It's a double-header with two guests. We start with Cineca's Andrew Emerson. As part of the EXSCALATE 4 COV EU-funded research project, he works of virtual screening of existing drugs regarding their potential efficacy against SARS-CoV-2. In part two we talk with Dan Jacobson of the Oak Ridge National Laboratory. He and his team used a big data analysis to understand how the virus "works", and they figured out very interesting mechanisms and pathways.

Humanity has always been exposed to potentially catastrophic risks that might endanger the continued existence of humanity. Asteroid impacts or supervolcano eruptions come to mind. But since about the invention of the atomic bomb, humanity has been able to wipe itself out, adding self-made existential risks to the natural ones. Oxford philosopher Toby Ord argues in his book The Precipice that those risks are much more likely than the natural ones. In this episode we explore this idea with him, and also discuss what we should do about this realization.

To conclude our detailed look at the ATLAS experiment, this episode looks at the computing infrastructure. We start out with the trigger systems that decide, very quickly, whether the data from a particular collision is worth keeping. We then discuss the reconstruction of the event, the simulation needed to understand the background as well as the LHC Grid used distribute data and computation over the whole planet. Our guest is CERN'n Frank Berghaus.

Guests: Philipp Windischhofer   Host: Markus Voelter   Shownoter: Andy er After understanding the history and development of ATLAS (and covering the LHC and particle physics in general) in previous episodes, we are now at the point where we can try to understand how a scientist uses the data produced by one of these large detectors and […]

ATLAS is one of the two general-purpose experiments at the LHC. It has been conceived, designed, and built over decades by hundreds of scientists and engineers from dozens of countries and hundreds of organizations. My guest, Peter Jenni, has been the head of the ATLAS collaboration for most of this time. In this episode we talk about science and engineering, but mostly about organizational aspects and the "community management" necessary to get such a magnificent machine off the ground.

The Lockheed F-35 Lightning II is going to be more or less what the F-16 and F-18 are today: the backbone of the US and NATO land and sea-based air forces. It is a multi-role fighter, and one of its versions has the capability to take off with a very short roll and land vertically. Tucker "Cinco" Hamilton is a test pilot who has flown all three versions of the jet. In this episode we talk about flying this fifth-gen fighter and about some aspects of the testing program.

In light of the current situation, we have decided to record a couple of episodes that cover some of the relevant background in of biology, medicine and healthcare. In this first episode we discuss emergency care and intensive care with a special focus on ventilation. We discuss these topics in general, and also specifically to COVID-19. Our guest, Kimon and Junad, are both practicing doctors and have practical experience with these topics.
